The Standard Cell Potential for the Nickel-Cadmium Battery Is 1 $\rightarrow$

The standard cell potential for the nickel-cadmium battery is 1.35 V, and the cell reaction can be written as 2 NiO(OH) (s) +2 H₂ O(l) + Cd(s) $\rightarrow$ 2 Ni(OH) 2 (s) + Cd(OH) 2 (s)
Which statement below is true based on the Nernst equation? Note: Q = reaction quotient, and
K = equilibrium constant for the cell reaction.

A) As the battery is used, the cell voltage approaches zero because Q approaches K in value.
B) When the battery no longer works, the cell voltage is zero because Q = K.
C) As the battery is used, the cell voltage does not change because Q equals 1.
D) When the battery is fully charged, Q K.
E) When the battery is fully charged, Q K.
